in complementary mode, offering flexibility in controlling
both turn-on and turn-off switching speeds.
The device has internal logic circuitry, which prevents
shoot-through during output state changes. The logic
inputs are protected against voltage spikes up to +14V,
regardless of V+ voltage. Propagation delay time is
minimized and matched between the inverting and
noninverting inputs. The device has very fast switching
times combined with very short propagation delays (8ns,
typ) making it ideal for high-frequency circuits.
The device operates from a +4V to +14V single power
supply, typically consuming 0.5mA of supply current and
has TTL input logic levels. This
device is available in a
6-pin SOT23 package and provides an upgrade path for
users of the MAX5048B.
